2019-01-14drm/i915: Markup paired operations on display power domainsChris Wilson
The majority of runtime-pm operations are bounded and scoped within a function; these are easy to verify that the wakeref are handled correctly. We can employ the compiler to help us, and reduce the number of wakerefs tracked when debugging, by passing around cookies provided by the various rpm_get functions to their rpm_put counterpart. This makes the pairing explicit, and given the required wakeref cookie the compiler can verify that we pass an initialised value to the rpm_put (quite handy for double checking error paths).

This patch resolves the DMC FW loading issue. Earlier DMC FW package have only one DMC FW for one stepping. But as such there is no such restriction from Package side.

But for second stepping and other steppings, offset is non zero number and is in dwords.

The case where the firmware isn't specified for a platform (although runtime PM works only with DMC on this platform) is the same case where the firmware is specified but can't be loaded for some reason. Hence we need to get a display init power domain ref in the first case too to keep the refcount bookkeeping in balance.

Some of the error messages from DMC load were too generic and may be confusing for the user. Lets explicitly add DMC words there. Also as homepage of DMC firmware is same as for the GuC and Huc, lets reuse URL definition.

2017-09-25drm/i915: Speed up DMC firmware loadingDavid Weinehall
Currently we're doing: 1. acquire lock 2. write word to hardware 3. release lock 4. repeat from 1 to load the DMC firmware. Due to the cost of acquiring/releasing a lock, and the size of the DMC firmware, this slows down DMC loading a lot. This patch simply acquires the lock, writes the entire firmware, then releases the lock. Testing shows resume speedups in the order of 10ms on platforms with DMC firmware (GEN9+). v2: Per feedback from Chris & Ville there's no need to do the whole forcewake dance, so lose that bit (Chris, Ville) v3: Actually send the new version of the patch... v4: Don't acquire the uncore lock. Disable preempt.
